Detailed Description

In the prior art shown in the above patent document, the arrangement in which the automatic loading feeder is fixed at the center of the holding portion is not necessarily the optimum arrangement, and the automatic loading feeder occupying two component reels per device has a limitation in the arrangement of the component reels, and therefore, in the case where the automatic loading feeder is arranged to be movable, there is a problem in that a large number of man-hours are required for the work of determining the arrangement of the component reels.

Accordingly, an object of the present invention is to provide a component reel arrangement determining method and a component reel arrangement determining device that can determine an optimal component reel arrangement.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The configurations, shapes, and the like described below are examples for explanation, and may be appropriately changed according to specifications of the component mounting device, the tape feeder, the carriage, the component reel, and the like. In the following, corresponding elements are denoted by the same reference numerals throughout the drawings, and redundant description thereof will be omitted. In fig. 1 and a part thereof to be described later, an X direction (a direction perpendicular to the paper surface in fig. 1) in a substrate transfer direction and a Y direction (a left-right direction in fig. 1) in the substrate transfer direction are shown as two axial directions orthogonal to each other in a horizontal plane. The Z direction (vertical direction in fig. 1) is shown as a height direction perpendicular to the horizontal plane.

First, the structure of the component mounting apparatus 1 will be described with reference to fig. 1. The component mounting apparatus 1 has a function of manufacturing a mounting substrate on which a component is mounted on a substrate. The substrate transfer mechanism 2 provided on the upper surface of the base 1a transfers the substrate 3 in the X direction and positions and holds the substrate. Above the substrate transfer mechanism 2, a mounting head 4 is provided which is moved in the horizontal direction (X direction, Y direction) by a head moving mechanism (not shown).

A plurality of tape feeders 6 are mounted on the upper portion of the carriage 5 coupled to the base 1a in the X direction on the side of the substrate conveyance mechanism 2. The tape feeder 6 is a component supply device that conveys the component storage tape 7 drawn out from the component reel 8 around which the component storage tape 7 is wound in a tape feed direction to supply components to a component pickup position of the mounting head 4, and the component storage tape 7 stores the components supplied to the component mounting device 1.

A plurality of upper reel holding portions 9U aligned in the X direction and a plurality of lower reel holding portions 9B aligned in the X direction are provided vertically below the tape feeders 6 on the front side of the carriage 5 (see fig. 2). The upper reel holding portion 9U and the lower reel holding portion 9B rotatably hold the component reels 8, respectively. A plurality of reel holders 20 are attached in front of the lower reel holding portion 9B so as to be aligned in the X direction. The reel holder 20 is attachable to and detachable from the carriage 5, and can hold each of the plurality of component reels 8. The carriage 5 is attachable to and detachable from the component mounting device 1, and a plurality of types of carriages 5 different in the number of tape feeders 6 and component reels 8 that can be held are prepared according to the mounted component mounting device 1.

In fig. 1, a main body cover 10 that can be opened and closed is provided above the carriage 5 so as not to allow an operator to contact with a movable mechanism such as the mounting head 4 during component mounting work. The component mounting device 1 includes a substrate transfer mechanism 2, a mounting head 4, and a mounting control unit 11 that controls a head movement mechanism. The mounting control unit 11 sends a component supply command to the tape feeder 6, controls the mounting head 4 and the head moving mechanism, and executes a component mounting operation in which the components supplied to the component pickup position by the tape feeder 6 are picked up by the mounting head 4, and the components are transferred to and mounted on the mounting position of the substrate 3 held by the substrate conveying mechanism 2.

The installation control unit 11 is connected to the management computer 13 via a wired or wireless communication network 12, and data can be transmitted and received between the installation control unit 11 and the management computer 13. The management computer 13 executes processes such as production management of a mounting substrate manufactured in a component mounting line including the component mounting device 1, management of resources such as the carriage 5, the tape feeder 6, and the component reel 8 used in the component mounting line, determination of the arrangement of the tape feeder 6 to the carriage 5, and determination of the arrangement of the component reel 8 to the carriage 5 and the reel holder 20.

Next, the structure and function of the carriage 5 according to the present embodiment will be described with reference to fig. 2. A feeder mounting portion 5a is provided at an upper portion of the carriage 5. A plurality of (here, 17) grooves S1 to S17 for mounting the tape feeder 6 are formed at equal intervals in the substrate conveyance direction (X direction) on the upper surface of the feeder mounting portion 5a in a state of being mounted on the component mounting device 1. 1 standard tape feeder 6L or 2 thin tape feeders 6S can be mounted in 1 slot S. In the slot S15, 2 thin tape feeders 6S are mounted. For convenience, the position of the left thin tape feeder 6S in the slot S15 is referred to as a slot S15L, and the position of the right thin tape feeder 6S is referred to as a slot S15R and the like.

In fig. 2, a plurality of (here, 17) lower reel holding portions 9B are formed below the feeder mounting portion 5a at equal intervals in the X direction so as to correspond to the positions of the respective slots S1 to S17. A plurality of (at most 17) upper reel holding portions 9U can be mounted at equal intervals in the X direction between the feeder mounting portion 5a and the lower reel holding portion 9B so as to correspond to the positions of the slots S1 to S17. The upper reel holding portion 9U is detachable and can hold one small component reel 8S having a small reel diameter.

The lower reel holding portion 9B can hold one small component reel 8S or one large component reel 8L having a large reel diameter. When the large component reel 8L is held by the lower reel holding portion 9B, the upper reel holding portion 9U cannot be mounted at the same position of the groove S that interferes with the held large component reel 8L. That is, when the large component reel 8L is held by the lower reel holding portion 9B, the small component reel 8S cannot be held at a position where the upper reel holding portion 9U can be mounted at the same position of the groove S.

In fig. 2, the reel holder 20 is fitted in front of the lower reel holding portion 9B between the positions of the slots S. The reel holder 20 attached to the carriage 5 can hold two small component reels 8S on the left and right sides, respectively, or can hold one large component reel 8L on the left and right sides, respectively. The position of the small-sized component reel 8S or the large-sized component reel 8L held by the reel holder 20 is located at any one of the left and right grooves S where the reel holder 20 is mounted (between the grooves S).

For example, the position of the component reel 8 held by the reel holder 20 fitted between the position of the slot S1 and the position of the slot S2 is the position of the slot S1 or the position of the slot S2. The reel holder 20 is mounted on the carriage 5 so as to be spaced apart from the component reels 8 mounted on the left and right reel holders 20 by a space that can ensure a working space for an operator.

Next, the structure and function of the reel holder 20 will be described with reference to fig. 3A and 3B. The reel holder 20 includes a plate-shaped arm portion 21 and a mounting portion 22. The reel holder 20 is fixed to the carriage 5 by attaching the attachment portion 22 to the carriage 5. The arm portion 21 is formed to extend upward from an upper portion of the mounting portion 22. The arm portion 21 is inclined outward in a state where the reel holder 20 is attached to the carriage 5. Upper pin mounting holes 23 and lower pin mounting holes 24 are formed in the upper and lower sides of the arm portion 21. Reel holding pins 25 are inserted into the left and right sides of the upper pin mounting hole 23 and the lower pin mounting hole 24. The reel holding pin 25 can be inserted into a core hole 8H formed in the center of the small component reel 8S or the large component reel 8L.

The reel holding pin 25 inserted into the lower pin mounting hole 24 can hold the small component reel 8S. The reel holding pin 25 inserted into the upper pin mounting hole 23 can hold the small-sized component reel 8S or the large-sized component reel 8L. Hereinafter, the component reel 8 is simply referred to as the component reel 8 when it is not necessary to distinguish between the small-sized component reel 8S and the large-sized component reel 8L. The position of the reel holding pin 25 inserted into the upper pin mounting hole 23 is referred to as an upper holding position of the reel holder 20, and the position of the reel holding pin 25 inserted into the lower pin mounting hole 24 is referred to as a lower holding position of the reel holder 20.

Next, an example of a layout that can be selected when the component reel 8 is disposed on the carriage 5 and the reel holder 20 attached to the carriage 5 will be described with reference to fig. 4A, 4B, 5A, and 5B. Fig. 4A shows the layout of the upper reel holding unit 9U and the lower reel holding unit 9B that hold the small component reel 8S at the same position in the same slot S, and the upper holding position and the lower holding position of the reel holder 20. Hereinafter, the plurality of upper reel holding portions 9U arranged in the arrangement direction (X direction) of the tape feeder 6 is referred to as a first holding row L1, the plurality of lower reel holding portions 9B arranged in the arrangement direction (X direction) of the tape feeder 6 is referred to as a second holding row L2, the upper holding positions of the plurality of reel holders 20 arranged in the arrangement direction (X direction) of the tape feeder 6 are referred to as a third holding row L3, and the lower holding positions of the plurality of reel holders 20 arranged in the arrangement direction (X direction) of the tape feeder 6 are referred to as a fourth holding row L4.

Fig. 4B shows a layout in which the small component reels 8S are held in the first holding row L1 and the second holding row L2, respectively, which are located in the same slot S, and the large component reels 8L are held in the third holding row L3. When the large-sized component reels 8L are held in the third holding row L3, there is a possibility that the large-sized component reels 8L and the component storage tapes 7 interfere with each other, and therefore the component reels 8 cannot be held in the fourth holding row L4 located in the same slot S.

Fig. 5A shows a layout in which the large component reels 8L are held in the second holding row L2 at the same position as the groove S, and the small component reels 8S are held in the third holding row L3. Fig. 5B shows a layout in which the large-size component reels 8L are held in the second holding row L2 located at the same position of the groove S, and the large-size component reels 8L are held in the third holding row L3. When the large-sized component reels 8L are held in the second holding row L2, there is a possibility that the large-sized component reels 8L and the component storage tapes 7 interfere with each other, and therefore the component reels 8 cannot be held in the first holding row L1 and the fourth holding row L4 located at the same position of the groove S.

Thus, the holding rows L1 to L4 hold the plurality of component reels 8. The carriage 5 and the reel holder 20 attached to the carriage 5 constitute a holding portion having a plurality of holding rows L1 to L4. The tape feeders 6 mounted on the carriage 5 are approached in the order of the first holding column L1, the second holding column L2, the fourth holding column L4, and the third holding column L3 at positions in a direction (Y direction) orthogonal to the direction (X direction) in which the tape feeders 6 (component supply devices) of the plurality of holding columns L1 to L4 are arrayed in the horizontal plane. The layout that can be selected when the component reel 8 is placed on the holding unit changes depending on the reel diameter of the component reel 8 placed on the holding unit.

Next, the automatic loading feeder 6A and the manual loading feeder 6M, which are the tape feeders 6 used by being mounted on the carriage 5, will be described with reference to fig. 6A and 6B. In fig. 6A, in the automatic loading feeder 6A, a component storage tape 7 (hereinafter, referred to as a "preceding tape 7 a") that supplies components to a component takeout position is inserted from an insertion port 6 Aa. In component replenishment, an operator pulls out the component storage tape 7 (hereinafter referred to as "subsequent tape 7 b") from the component reel 8 for component replenishment and inserts the component storage tape into the upper portion of the insertion port 6Aa into which the preceding tape 7a is inserted. The leading tape 7a is supplied from one component reel first used by the component supply apparatus. In addition, the subsequent tape 7b is supplied from the component reel next used by the component supply apparatus among the plurality of component reels.

When the component supply is continuously performed so that the preceding tape 7a has no component, the automatic carry-in feeder 6A automatically switches the component storage tape 7, which supplies the component, to the subsequent tape 7b to continue the component supply. In this way, the automatic carry-in feeder 6A automatically switches and supplies the plurality of component storage tapes 7 (the preceding tape 7a and the succeeding tape 7 b) drawn out from and inserted into the plurality of component reels 8.

In fig. 6B, in the manual carry-in feeder 6M, the preceding tape 7a is inserted from the insertion port 6Ma to supply the component to the component take-out position. When the remaining amount of the leading tape 7a inserted from the insertion port 6Ma becomes small, component replenishment is performed by an operator. In the component replenishment, the operator pulls out the post tape 7b from the component reel 8 for component replenishment, and joins the leading end portion of the post tape 7b to the trailing end portion of the preceding tape 7a by the lap tape T. The engaged succeeding tape 7b follows the preceding tape 7a and is carried to the manual carry-in feeder 6M, so that component supply is continued.

A plurality of types such as standard and thin types are prepared in the automatic loading feeder 6A and the manual loading feeder 6M in accordance with the tape width of the conveyed component storage tape 7. Hereinafter, the automatic loading feeder 6A and the manual loading feeder 6M are referred to as the tape feeders 6 without distinguishing the tape width of the conveyed component storage tape 7 or the like.

Next, the arrangement of the component reels 8 that store the preceding tape 7A and the succeeding tape 7B supplied to the automatic carry-in feeder 6A mounted on the carriage 5 will be described with reference to fig. 7A and 7B. In fig. 7A, the small component reels 8S that store the preceding tape 7A are arranged in a first holding line L1, and the small component reels 8S that store the succeeding tape 7b are arranged in a second holding line L2 that is further from the automatic loading feeder 6A than the first holding line L1. In fig. 7B, the large-sized component reels 8L that store the preceding tape 7a are arranged in the second holding row L2, and the large-sized component reels 8L that store the succeeding tape 7B are arranged in the third holding row L3 that is further from the automatic loading feeder 6A than the second holding row L2.

That is, the component reels 8 that store the preceding tape 7a used in the component supply device (automatic carry-in feeder 6A) are arranged closer to the holding line L of the component supply device in the direction orthogonal to the direction in which the component supply device is arranged in the horizontal plane in the holding portion (carriage 5) than the component reels 8 that store the succeeding tape 7b used subsequently. Thereby, the preceding tape 7a inserted at the lower portion of the insertion port 6Aa of the automatic loading feeder 6A and the succeeding tape 7b inserted at the upper portion of the insertion port 6Aa can be prevented from interfering with each other.

Next, the configuration of the processing system of the management computer 13 will be described with reference to fig. 8. The management computer 13 includes a processing unit 30, a storage unit 31, an input unit 32, a display unit 33, and a communication unit 34. The input unit 32 is an input device such as a keyboard, a touch panel, or a mouse, and is used when various commands and data are input. The display unit 33 is a display device such as a liquid crystal panel, and displays various data and input screens. The communication unit 34 is a communication interface, and transmits and receives data between the management computer 13 and devices constituting the component mounting line including the component mounting device 1 via the communication network 12.

The storage unit 31 is a storage device that stores production data 31a, production line information 31b, component reel information 31c, holding unit information 31d, feeder arrangement information 31e, restriction condition information 31f, component reel arrangement 31g, and the like. The processing unit 30 includes an information acquisition unit 35 and a component reel arrangement determination unit 36 as internal processing units.

The production data 31a includes information necessary for mounting components on the substrate 3, such as the number of produced substrates 3 for each type of mounting substrate produced, the component name (type) of the component mounted on the substrate 3, and the mounting position (XY coordinate). The line information 31b includes information of devices constituting the component mounting line, such as the types of the mounting head 4 and the carriage 5 that can be mounted on the component mounting device 1. The component reel information 31c includes information for specifying the component reel 8 used in the component mounting line.

Here, an example of the component reel information 31c will be described with reference to fig. 9. The component reel information 31c includes a "reel number" 41, a "reel diameter" 42, an "accommodation bandwidth" 43, and a "component name" 44. The "reel number" 41 is a number that determines the component reel 8. "reel diameter" 42 is information that determines the reel diameter of component reel 8. In this example, "S" represents a small diameter (small component reel 8S), and "L" represents a large diameter (large component reel 8L).

The "storage tape width" 43 indicates the tape width of the component storage tape 7 wound and stored on the component reel 8. The "component name" 44 is a name of a component for specifying the component stored in the component storage tape 7. For example, the component reel 8 having the "reel number" 41 of "RS101" is a small component reel 8S that stores a component having a component name "D1234" and a component storage tape 7 having a bandwidth of 4 mm.

In fig. 8, the holding unit information 31d includes information on a layout that can be selected when the component reel 8 is disposed in the holding unit for each type of holding unit (carriage 5, reel holder 20). Here, an example of the holding section information 31d will be described with reference to fig. 10. The holding section information 31d shown in fig. 10 indicates a combination (layout) of the component reels 8 that can be held in the first holding row L1, the second holding row L2, the third holding row L3, and the fourth holding row L4 at the same positions of the grooves S in the holding sections shown in fig. 4A, 4B, 5A, and 5B. The holding portion information 31d includes a "layout number" 51, a "first holding column L1"52, a "second holding column L2"53, a "third holding column L3"54, and a "fourth holding column L4"55.

The "layout number" 51 is a number for specifying the combination (layout) of the component reels 8. "first holding row L1"52, "second holding row L2"53, "third holding row L3"54, and "fourth holding row L4"55 indicate whether the component reel 8 held in each of the holding rows L1 to L4 is a small-sized component reel 8S (S), a large-sized component reel 8L (L), or a component reel 8 (-) is not held. For example, the layout with "layout number" 51 being "#1" corresponds to the layout shown in fig. 4A in which small component reels 8S are held in all of the holding rows L1 to L4. Similarly, the layout whose "layout number" 51 is "#16" corresponds to the layout of fig. 4B, the layout of "#20" corresponds to the layout of fig. 5A, and the layout of "#22" corresponds to the layout of fig. 5B.

In fig. 8, the feeder arrangement information 31e includes arrangement information of the component supply device (tape feeder 6) arranged in advance in the carriage 5, and the component supply device 5 supplies the component storage tape 7 drawn out from the component reel 8 arranged in the holding portion (carriage 5, reel holder 20). Here, an example of the feeder arrangement information 31e in which the automatic loading feeder 6A and the manual loading feeder 6M are arranged on the carriage 5 shown in fig. 2 will be described with reference to fig. 11. In the feeder configuration information 31e, "feeder number" 62, "feeder type" 63, and "carrying bandwidth" 64 of the tape feeder 6 determined to be fitted to the slot S are stored in a manner corresponding to the "slot number" 61 determining the position of the slot S of the carriage 5.

The "feeder type" 63 indicates whether the tape feeder 6 is an automatic loading feeder 6A (automatic) or a manual loading feeder 6M (manual). The "conveyance bandwidth" 64 indicates a bandwidth of the component storage tape 7 conveyed by the tape feeder 6. For example, the automatic loading feeder 6A having "feeder number" 62 of "FA101" to which the component storage tape 7 having a carrying bandwidth of 4mm is attached is mounted in the slot S1L having "slot number" 61 of "S1L". In addition, a manual loading feeder 6M having "FM201" as the "feeder number" 62 of the component storage tape 7 having a carrying tape width of 8mm is fitted to the slot S6.

In fig. 8, information related to the restriction condition, which is the restriction condition regarding the component supply device (tape feeder 6) and the component storage tape 7 supplied thereto, is included in the restriction condition information 31 f. More specifically, the manufacturing condition information 31f includes a relative positional relationship between the tape feeder 6 mounted on the holding portion and the component reel 8 storing the component storage tape 7 supplied to the tape feeder (hereinafter referred to as "feeder-reel relationship") for each kind of the holding portion (the carriage 5, the reel holder 20), for example, as an undisplaceable feeder-reel relationship, there is a case where an angle at which the component storage tape 7 pulled out from the component reel 8 enters the insertion ports 6Aa, 6Ma of the tape feeder 6 is larger than a predetermined angle.

The manufacturing condition information 31f includes a relative positional relationship (hereinafter referred to as a "reel-reel relationship") of the plurality of component reels 8, and the plurality of component reels 8 store the component storage tapes 7 supplied to the plurality of tape feeders 6 mounted on the holding portion. For example, as a reel-to-reel relationship that cannot be arranged, there is a case where one component storage tape 7 drawn out from one component reel 8 interferes with (comes into contact with) another component storage tape 7 drawn out from another component reel 8.

Here, an example of the constraint conditions relating to the feeder-reel relationship when the component reels 8 are arranged on the holding portion as shown in fig. 4A, 4B, 5A, and 5B will be described with reference to fig. 12. In the constraint condition information 31f relating to the feeder-reel relationship, the holding columns L1 to L4 that can place the component reels 8 at the positions of the corresponding tanks S are stored so that the "first holding column L1"72, "the" second holding column L2"73," the "third holding column L3"74, "and the" fourth holding column L4"75 correspond to the" tank relative position "71 that specifies the position of the tank S corresponding to the component reel 8 with respect to the tank S to which the target tape feeder 6 is mounted.

In the "groove relative position" 71, "0" represents the position of the groove S equipped with the tape feeder 6, and "± 1" represents the position of the groove S of the adjacent one of the grooves S equipped with the tape feeder 6. In the "first holding line L1"72, the "second holding line L2"73, the "third holding line L3"74, and the "fourth holding line L4"75, a case where the component reel 8 can be arranged is indicated by "o", and a case where the component reel 8 cannot be arranged is indicated by "x". For example, in the first holding column L1, it is shown that the component reels 8 can be arranged at the positions of the grooves S where the tape feeders 6 are mounted and the adjacent one of the grooves S, but the component reels 8 cannot be arranged at positions separated by two ("± 2") or more of the grooves S.

Next, an example in which the component reel 8 can be disposed on the carriage 5 and an example in which the component reel 8 cannot be disposed on the carriage 5 will be described with reference to fig. 13A, 13B, and 13C. Fig. 13A, 13B, and 13C show an example in which a small-sized component reel 8Sv that stores a component storage tape 7v supplied to a tape feeder 6v mounted on a groove S7 of the carriage 5 and a small-sized component reel 8Sw that stores a component storage tape 7w supplied to a tape feeder 6w mounted on a groove S8 of the carriage 5 are disposed in the first holding row L1 or the second holding row L2.

Fig. 13A is an example of the arrangement, and a small-sized component reel 8Sv is arranged in the first holding line L1 at the position of the adjacent one of the grooves S6 of the groove S7 to which the tape feeder 6v is mounted. The small-sized component reels 8Sw are arranged in the second holding row L2 at positions separated from the two slots S6 from the slot S8 on which the tape feeder 6w is mounted. The arrangement positions of the small component reel 8Sv and the small component reel 8Sw both satisfy the constraint condition information 31f (feeder-reel relationship) shown in fig. 12. The component storage tape 7v and the component storage tape 7w do not intersect each other, and the restriction condition information 31f (reel-reel relationship) is satisfied.

Fig. 13B is an example of the impossibility of arrangement, in which the small-sized component reels 8Sv are arranged in the first holding row L1 at positions separated by two slots S5 from the slot S7 to which the tape feeder 6v is mounted. The small-sized component reels 8Sw are arranged in the second holding row L2 at a position away from the three tanks S5 from the tank S8 on which the tape feeder 6w is mounted. The arrangement positions of the small component reel 8Sv and the small component reel 8Sw do not satisfy the restriction condition information 31f (feeder-reel relationship) shown in fig. 12.

Fig. 13C shows an example in which the arrangement is impossible, and the small-sized component reel 8Sv is arranged in the second holding row L2 at the position of the adjacent one of the grooves S8 of the groove S7 to which the tape feeder 6v is mounted. The small-sized component reels 8Sw are arranged in the second holding row L2 at a position separated from the two tanks S6 from the tank S8 on which the tape feeder 6w is mounted. The arrangement positions of the small component reel 8Sv and the small component reel 8Sw both satisfy the restriction condition information 31f (feeder-reel relationship) shown in fig. 12. However, the component storage tape 7v and the component storage tape 7w intersect (interfere), and the restriction condition information 31f (reel-reel relationship) is not satisfied.

In this way, the restriction condition information 31f includes a relative positional relationship (feeder-reel relationship) of the component supply device (tape feeder 6) and the component storage tape 7 supplied to the component supply device, and a relative positional relationship (reel-reel relationship) of the plurality of component storage tapes 7. It should be noted that the feeder-reel relationships included in the restriction condition information 31f are applied between the manual loading feeder 6M and the component reel 8, between the automatic loading feeder 6A and the component reel 8 that houses the preceding tape 7a, and between the automatic loading feeder 6A and the component reel 8 that houses the succeeding tape 7b, respectively.

In fig. 8, the information acquisition unit 35 acquires various information for determining the component reel arrangement for arranging the component reels 8 on the holding unit, based on the production data 31a, the production line information 31b, the component reel information 31c, the holding unit information 31d, the feeder arrangement information 31e (arrangement information of the component supply device), and the restriction condition information 31f stored in the storage unit 31.

The component reel arrangement determination unit 36 determines the component reel arrangement for arranging the component reels 8 on the carriage 5 (holding unit) on which the component supply device (tape feeder 6) is mounted in advance, based on the acquired various information, and stores the component reel arrangement in the storage unit 31 as the component reel arrangement 31g. More specifically, the component reel arrangement determining section 36 arranges the component reels 8 on the holding section so as to satisfy the constraint condition information 31f, based on the selectable layouts included in the "slot number" 61, "feeder type" 63, "carrying bandwidth" 64, the configuration of the holding section, the "reel diameter" 42, "storage bandwidth" 43, "component name" 44, and the holding section information 31d of the tape feeders 6 mounted on the holding section (carriage 5, reel holder 20) included in the feeder arrangement information 31e, the component reel arrangement information 31c, and the holding section information 31 d.

For the automatic load feeder 6A in which the "feeder type" 63 is "automatic", the component reel arrangement deciding part 36 decides the arrangement of the component reel 8 that supplies the preceding tape 7a and the component reel 8 that supplies the succeeding tape 7b. That is, the component reel arrangement is made for each carriage 5 (each holding portion) mounted on the apparatus (component mounting apparatus 1) constituting the component mounting line, including the component reel 8 used in one component supply apparatus (tape feeder 6) and the component reel 8 used subsequently. The component reel arrangement determination unit 36 displays the determined component reel arrangement on the display unit 33 or a portable terminal (not shown) carried by the operator. In addition, when there is a component reel 8 that cannot be placed, the component reel placement determination unit 36 reports the content to the display unit 33 or the mobile terminal.

Here, an example of distributing the component reel arrangement 31g of the component reel 8 to the holding portion (carriage 5) as shown in fig. 4A, 4B, 5A, and 5B based on the component reel information 31c shown in fig. 9, the holding portion information 31d shown in fig. 10, the feeder arrangement information 31e shown in fig. 11, and the restriction condition information 31f shown in fig. 12 will be described with reference to fig. 14 and 15. Fig. 14 shows a configuration of a holding section where the component reel 8 is disposed, and shows holding rows L1 to L4 in which the component reel 8 can be disposed at the position of the groove S of the "groove number" 81. In "first holding row L1"82, "second holding row L2"83, "third holding row L3"84, and "fourth holding row L4"85, a case where component reel 8 can be arranged is represented by "o", and a case where component reel 8 cannot be arranged is represented by "-".

In fig. 14, reel holders 20 are attached to the carriage 5 at positions between the grooves S1 and S2, between the grooves S4 and S5, between the grooves S7 and S8, between the grooves S10 and S11, and between the grooves S16 and S17, respectively. Accordingly, the positions of the grooves S1, S2, S4, S5, S7, S8, S10, S11, S16, and S17 enable the component reels 8 to be arranged not only in the first holding row L1 and the second holding row L2 but also in the third holding row L3 and the fourth holding row L4.

Fig. 15 shows the component reel arrangement 31g determined by the component reel arrangement determination unit 36. In "first holding line L1"91, "second holding line L2"92, "third holding line L3"93, and "fourth holding line L4"94 corresponding to the position of slot S of "slot number" 81, information relating to the component reel 8 that is arranged is shown, and the position where the component reel 8 is not arranged is shown as "-". Included in the information relating to the component reels 8 that are arranged are information that determines the "reel number" 41 of the component reel 8, information (slot number) of the tape feeder 6 that determines the insertion of the housed component-housing tape 7, and information that determines whether the housed component-housing tape 7 is the preceding tape 7a (a) or the succeeding tape 7B (B).

For example, a small component reel 8S having a "reel number" 41 of "RS101" is disposed in the first holding line L1 at the position of the slot S1, and the component reel 8S stores the leading tape 7a supplied to the automatic carry-in feeder 6A mounted in the slot S1L. Further, a small-sized component reel 8S having "reel number" 41 of "RS103" is disposed in the second holding row L2 at the position of the slot S1, and this component reel 8S stores the succeeding tape 7b supplied to the automatic loading feeder 6A mounted in the slot S1L.

Next, another example of the component reel arrangement 31g determined by the component reel arrangement determination unit 36 will be described with reference to fig. 16. In this example, the component reel arrangement 31g is created based on the position (holder number) where the component reel 8 provided on the carriage 5 (holder) is arranged. In "first holding line L1"102, "second holding line L2"103, "third holding line L3"104, and "fourth holding line L4"105 corresponding to "holder number" 101, information relating to the component reels 8 that are arranged is shown, and a position at which the component reels 8 are arranged is represented as "-".

Each holding column includes "reel number" 41, "reel diameter" 42, "tape position" information 106, and "preceding/succeeding" information 107. The "reel number" 41 is a number that determines the component reel 8. The "reel diameter" 42 includes information for determining whether the component reel 8 is the small component reel 8S (S) or the large component reel 8L (L). Information that determines the position of the tape feeder 6 (insertion position of the tape) equipped with the component storage tape 7 stored by the component reel 8 is included in the "tape position" information 106.

For example, "S05" indicates that the component storage tape 7 is mounted to the tape feeder 6 mounted at S5. In addition, in the case of a double feeder capable of supplying two component reels 8 in parallel using one manual loading feeder 6M, as indicated by "3" and "4" of the "holder number" 101, it is also indicated whether the insertion position of the component storage tape 7 of the tape feeder 6 is the left side (L) or the right side (R). Similarly, in the case of the thin tape feeder 6S, as indicated by "1" and "2" of the "holder number" 101, the position of the mounted slot S is also indicated on the left side (L) or the right side (R).

The "preceding/succeeding" information 107 includes information for determining whether the component storage tape 7 stored on the component reel 8 is the preceding tape 7a (a) or the succeeding tape 7B (B). As in the component reel arrangement 31g shown in fig. 16, when the number of the grooves S in which the tape feeders 6 are arranged is different from the number of the positions at which the component reels 8 are arranged based on the holder number, visibility when the worker arranges the component reels 8 is improved.

The component reel arrangement 31g thus determined is displayed as a distribution list on the display unit 33, a portable terminal held by an operator, or a display unit (not shown) included in the component mounting apparatus 1. The component reel arrangement 31g shown in fig. 15 and 16 is only an example of a case where the reel holder 20 is used, and the component reel arrangement 31g displays only the first holding sequence L1 and the second holding sequence L2 when the reel holder 20 is not used.

Next, a method of determining the arrangement of the component reel for arranging the holding portion on the component reel 8 will be described according to the flow of fig. 17. First, the information acquiring portion 35 acquires the component reel information 31c, the holding portion information 31d, the feeder arrangement information 31e (arrangement information of the component supply device), and the restriction condition information 31f (ST 1). Next, the component reel arrangement determination unit 36 determines the component reel arrangement for arranging the component reels 8 in the holding unit, based on the acquired information (ST 2). The component reel layout determination unit 36 stores the determined component reel layout as the component reel layout 31g, and displays it on the display unit 33 or the portable terminal. In addition, when there is a component reel 8 that cannot be placed, the component reel placement determination unit 36 reports this to the display unit 33 or the mobile terminal.

As described above, the management computer 13 of the present embodiment includes: an information acquisition unit 35 that acquires component reel information 31c including information identifying the component reels 8 to be used, holding unit information 31d including information on a layout that can be selected when the component reels 8 are arranged on the holding unit, arrangement information (feeder arrangement information 31 e) of a component supply device (tape feeder 6) arranged on the holding unit, and restriction condition information 31f on the component supply device and a component storage tape 7 supplied to the component supply device; and a component reel arrangement determination unit 36 that determines the arrangement of the component reels including the component reel 8 used in one component supply device and the component reel 8 used subsequently, and the management computer 13 of the present embodiment is an arrangement determination device of the component reels that determines the arrangement of the component reels. This makes it possible to determine an optimal component reel arrangement.

In the above description, the reel diameters of the component reel 8 are two types, i.e., the small-sized component reel 8S and the large-sized component reel 8L, but the reel diameters of the component reel 8 are not limited to two types, and those skilled in the art will understand that: even when three or more types of component reels 8 are included, the optimal arrangement of the component reels 8 can be determined. Additionally, those skilled in the art will understand that: modifications of the carriage 5 and the reel holder 20 constituting the holding portion are also included in the scope of the present invention.

In addition, the combination of the component reel 8 and the tape feeder 6 constituting the component supply unit U may be set in advance, or an appropriate combination may be determined based on the production data 31 a. In the case of setting in advance, since the feeder type information to be used is also included in the parts reel information 31c on the parts reel 8, the tape feeder 6 to be combined is determined based on the parts reel information 31c on the parts reel 8. In addition, when the combination is performed based on the production data 31a, the number of components used is predicted based on the number of produced substrates 3 and the component names (types) of the components mounted on the substrates 3, and based on the resource information 31c, the automatic loading feeder 6A and the component reel 8 are combined if additional supply is necessary, and the manual loading feeder 6M and the component reel 8 are combined if additional supply is not necessary, thereby determining the tape feeder 6 to be combined.

In the above description, although the removable reel holder 20 is attached to the carriage 5 to hold the large-sized component reels 8L having a large reel diameter in the plurality of holding rows located in the same slot S, the reel holder 20 does not need to be attached when the carriage 5 is used to hold the large-sized component reels 8L having a large reel diameter in the plurality of holding rows located in the same slot S.
